The sum of a number and 5, less than 10, is 3.

Answers

Answer 1

Answer: The sum of a number and 5, less than 10, is 3 can be expressed as:

x + 5 - 10 = 3
where x is unknown number.

x + 5 = 3 + 10
x + 5 = 13
x = 13 - 5
x = 8

Rewrite the equation by completing the square.
4x2 + 28x + 49 = 0
(x+) =

Answers

Answer: x = - 3.5

Step-by-step explanation:

Rewrite the equation by completing the square.

4x2 + 28x + 49 = 0

Completing the square method :

Divide through by the Coefficient of x^2

x^2 + 7x + (49/4) = 0

a = 1, b = 7, c = 49/4

Move c to the right side of the equation

x^2 + 7x = - 49/4

Complete the square on the left hand side by squaring its half of the x term

(7/2)^2 = (49/4)

Add the output to both sides of the equation

x^2 + 7x + (49/4) = - (49/4) + (49/4)

(x + 7/2)^2 = 0

Square root of both sides

x + 7/2 = 0

x = - 7/2

Find the distance between points m(-4,6) and n(10,-5). round to the nearest tenth if necessary.

Answers

Use distance formula; $d = √((x_1-x_2)^2 + (y_1 - y_2)^2)$

You have $x_1 = -4$ , $x_2 = 10$ , $y_1 = 6$ , and lastly $y_2 = -5$

Plug in these values;

$d = √((-4-10)^2 + (6 - (-5))^2)$
$d = √((-14)^2 + (6 +5))^2)$
$d = √(14^2 + 11^2)$
$d = √(317)$
$d=17.8044938\ldots$
$d \approx \boxed{17.8}$

Answers

Remember order of operations. Please (Parenthesis and brackets) Excuse (exponents) My (multiplication) Dear (Division) Aunt (Add) Sally (Subtract). Also remember that multiplication and division as well as addition and subtraction should go from left to right. So if you were to do this problem first I'd convert the fraction 1/10 to a decimal. That's like saying 1 in 10 or 10%. So it should convert to .10 x 6 = 0.60 and don't forget to multiple 7 x1000 next. (Left to right). 7,000. So it becomes 5+10+0.60+7,000 then add. 7,015.60 is your answer.
